BOX-SHOOK-COUNTING MACHINE. a

Specification of Letters Patent.

Patented Aug. 15, 1916.

Application filed January 5, 1915. Serial No. 575.

T 0 all whom it may concern:

Be it lmown that I, EDWARD P. DUNBAR, a citizen ,of the United States, and a. resident of Seattle, in the county of King and State of W ashingtOn, have invented an Improvement in BoX-Shook-Counting Machines, of which the following is a specification.

My present invention relates to a machine designed to mechanically count boxshooks and arrange them in bundles of predetermined numbers, upon their delivery from a resaw machine.

In the box manufacturing industry the shocks are discharged from either a single or twin band resaw machine now generally in use and counted and arranged in bundles of predetermined numbers by hand, thus requiring considerable labor and in volving certain disadvantages in loss of time and as a result of errors in the handling and counting of the shocks.

The object of my invention is therefore to provide a machine which will effect saving of labor and time, which will be readily adjustable both to varying sizes of shocks and to count bundles of various numbers, which will be wholly automatic in its operation, which will receive the shoo-ks from either a single or twin band resaw machine Without the necessity for an intermediary, and by the means of which the disadvantage resulting from errors in the count will be wholly eliminated.

In carrying out these objects I provide a construction and arrangement of parts as shown in the accompanying drawings and which, with the operation thereof will be clearly apparent from the following description.

In these drawings, Figure 1 is a side elevation. Fig. 2 is a vertical transverse. section taken substantially on line 2-2 of Fig. 1, and Fig. 3 is a similar view taken through the two frame pieces and the vertically adjustable retaining board only.

Referring now to these figures, the frame of my improved machine consists essentially of two spaced side walls A and A, these walls being substantially parallel and having inner opposing flat faces and outer angle beams 4; extending longitudinally along their upper and lower edges.

As seen in Fig. 3, the walls A and A are provided with alined vertical slots in order to receive transverse supporting arms B therethrough, thesearms receiving the retaining board B for the counted bundles of shocks and being adapted to support such board in vertically adjustable relation between the rear portions of the walls A and A.

To the end that the supporting arms B may be readily adjusted, they are provided at one end with tubular internally threaded bearings b engaged upon upright threaded adjusting shafts C, these shafts being journaled upon the outer surface of the side wall A and having their upper ends connected by gears c to the ends of av longitudinal connecting shaft C and one of the said shafts C having a hand wheel C at its upper end whereby they may be simul taneously rotated to raise and lower the supporting arm B at the same time.

The frame wall A is rigidly connected at its lower longitudinal edge to the upper portions of short standards or supporting posts A in turn bolted to a floor or bed plate A while the lower edge of the opposite wall A is provided with bearings a internally threaded and engaged upon horizontal threaded adjusting shafts D connected by a geared horizontal connecting shaft D and one of which is provided with an adjusting hand wheel D whereby they may be simultaneously rotated in order to adjust the frame wall A toward and away from the other frame wall A in order to accommodate shooks of various widths.

The walls A and A carry lower bearings c for the horizontal rack portions E of bundle ejecting arms E, one of which is disposed closely adjacent tothe inner surface of each of the side walls A and A at its forward end, the rack portions E of these ejecting arms being engaged by a pair of gear wheels F splined upon the main driving shaft F, disposed horizontally and transversely below the frame walls A and A in bearings, indicated at f.

On the shaft Fis loosely mounted apulley F which is suitably connected as by a belt to the feed roll gear shaft of a resaw machine, a part of the frame G of which is shown in Fig. 1. At one side the pulley F is provided with a clutch face f with which a clutch face it mounted on a sleeve h is adapted to cooperate, this sleeve h being also splined on the shaft F and movabletoward and away from the pulley F in order to respectively engage and disengage the clutch, through the action of a pivoted yoke lever 71- connectedby a small link 72; to the short upright arm of a bell crank lever H, one arm of which extends horizontally beneath the frame walls A and A and has its extremity disposed beneath a vertically movable trip rod 1 journaled in bearings along the outer surface of the frame wall A and normally held in its upper inoperative position by a spring I.

Hinged to the upper forward portion of the frame wall A is a forwardly projecting adjustable bracket or leaf J which extends to a point adjacent the frame G of the resaw machine and is adapted to receive the shooks as they are discharged from the resaw machine, the shooks being guided in their passage in alinement and in end to end relation across the bracket or leaf J by means of a spring J pressing thereon. The successive shooks are forced steadily across the bracket or leaf J and on to a receiving table K vertically adjustably mounted between the for ward portions of the upright walls A and A and of sufficient width to permit of the passage of the ejecting arms E between the side edges of the table and the said frame walls as will be seen by reference to Fig. 2.

The table K is secured to the upper ends of uprights K extending vertically between the frame walls A and A and jo-urnaled through bearings attached to the side wall A, the lower extremities of uprights being connected by a bar L" having an intermediate arm is to which one end of a flexible counter balance K including a counter balancing weight 70 is connected.

The lower portions of the upright K are movable vertically through slots in the flooring or bed plate A as is also the counter balancing weight E for the ejecting arms E. Vertical movement of the receiving table K is effected by means of springs K bearing thereon to force the same downwardly with each shook as it is received thereon until the desired number, constituting the bundle, are in place.

Mounted on a shaft L, supported upon a bracket L upstanding from the frame wall A is a revoluble dial L having an annular series of numbered apertures Z, in a selected one of which a pin M may be disposed as shown in Fig. 2. The dial also has a ratchet wheel Z with which engages a gravity pawl 71 intermediately pivoted on the upper end of a ratchet lever N, said lever being intermediately fulcrumed upon the shaft L to swing thereon and having its lower end rigidly connected to a detent arm n, the forward end of which is disposed toreceive the rear end of each of the shooks thereagainst and projects just a sufficient distance into the path of movement of the shooks to rotate ratchet wheel Z one tooth upon its actuation by each shook as received on to the table K. A spring controlled pawl 0 mounted upon a bracket 0 extending from the support L also engages the ratchet wheel Z so as to prevent return movement thereof by means of the counter balancing weight L for the dial.

A trip rod P is journaled at its inner end upon the shaft L and extends forwardly upon the upper end of the trip rod I so that the pin M in a selected aperture Z of the dial bears downwardly upon this trip arm in order to force the trip rod I downwardly, when the desired number of shooks have accumulated upon the gradually depressed receiving table K. Vertically along the outer surface of the frame wall A is also mounted a releasing rod Q, normally held in upper inoperative position by spring Q, the upper end of which is provided with'an angular-1y projecting piece Q disposed above the two ratchet engaging pawls n and 0, and the lower end of which is provided with an angular arm 9 extending beneath the horizontal rack portion E of one of the ejecting arms E this rack portion of the arm having a cam e which, during the rearward movement of the ejecting arms in order to move the bundle of shooks from the receiving table K to the retaining board B, comes into en agement with the lower angular arm 1 and forces the releasing rod Q to lower so that the upper arm (1 of this rod releases the pawls n and 0 from the ratchet wheel of the dial L and permits the latter to rotate rearwardly to its original position under actuation of its counter balancing weight L Thus the stock which is fed from the frame G of the resaw machine is gradually piled up on the receiving table K which lowers with the reception of each piece thereof, each piece of stock causing the proper movement of the dial through contact thereof with detent n and consequent swingii'ig n'iovement of ratchet lever N. When the desired number of pieces have been thus accumulated on the receiving table the pin M comes into engagement with the trip arm P, forcing the latter down against the upper end of the trip rod 1 and imparting a downward thrust to the latter against the tension of its return spring I which causes engagement of the clutch members 71, and 7" through the means previously described in order to couple the pulley F to the shaft F and in this manner start rotation of the latter. Movement is thus communicated to the rack bars E through the gears F causing rearward movement of the ejector arms E in order to thrust the bundle or pile of shooks 0E of the receiving table K on to the retaining board B which has been previously adjusted to the horizontal plane which the receiving table K occupies when the desired number of pieces are piled thereon. The bundle is then removed from the retaining board B and properly tied.

During rearward movement of the rack bars E, the cam c of one of them depresses the releasing rod Q, as before described which permits reverse movement of the dial L through the release of the pawls engaging the dial ratchet relieves the pressure upon the trip red I which moves upwardly under the actuation of its spring and permits the clutch faces 7i and f to be separated by a spring 7L arranged between them. The power being thus relieved, the ejector arms E are returned to their normal positions as shown in Fig. 1 through the action of their counter balance E the receiving table K having been previously raised to normal position as shown, when the bundle is moved to the retaining board B, through the action of the counter weight Thus it will be seen that I provide a highly effective device, one which is adjustable in order to accommodate stock of various sizes, one which is further adjustable in respect to the number of pieces accumulated in each bundle, and one which will constantly operate in a manner wholly automatic and without mistake.
